A lamp optic () for a lamp includes a proximal end (), a distal end () and a longitudinal axis (L). The proximal end () has a proximal inner side wall () linearly extending toward the distal end () and intersecting a proximal flat portion (). The distal end () has a distal inner side wall () linearly extending toward the proximal end () and intersecting a distal flat portion (). The distal flat portion length (LD) is at least 25 percent of the proximal flat portion length (LP). A lateral side () extends from the proximal end () to the distal end (). The lateral side () has a first skirt region () and a second skirt region (). The first skirt region () and the second skirt region () extend linearly and successively from the proximal end () to the distal end ().

Lamp optic for use in LED-based lamp

Lamp optic for a vehicle lamp

An illumination apparatus () for use with a vehicle () includes a lighting system () and a controller (). The lighting system () includes at least three light engines (). The controller () is configured to simultaneously illuminate at least two of the light engines () while simultaneously not illuminating at least one of the light engines () upon activation of the illumination apparatus. The controller () is further configured to alternate which of the light engines () are not illuminated and which two of the light engines () are simultaneously illuminated such that at least two light engines () are simultaneously illuminated during the entire illumination sequence. As such, at least two light engines () are illuminated upon activation of the illumination apparatus ().

Sequential vehicle signaling system and method

A vehicle light assembly may be made from a lamp having a plurality of LED light sources arrayed circumferentially around the lamp; a reflector body having a reflector axis generally directed to a field to be illuminated. A plurality of reflective surfaces is formed on the front side, the respective reflective surfaces separated by one or more axially extending walls. A through passage is formed in the reflector body, sized and shaped to receive a portion of the lamp, and intersecting a planar extension of at least one of the axially extending walls separating a first reflective surface from a second reflective surface. The planar extension intersects the lamp between a first LED and a second LED whereby light form the first LED substantially shines toward the first reflective surface and the light from the second LED shines toward the second reflective surface.

Multi-color or multi-function LED vehicle light assembly

A lamp, and a method of assembling the lamp, includes a heat sink, a heat conductive post extended longitudinally from the heat sink where the post has longitudinal faces that each has a longitudinally extending slot therein, a metal clad circuit board slid into each slot so that each circuit board is in thermal communication with the post where each circuit board has an exterior surface with an LED thereon, and a cap on top of the post where the cap abuts lateral end surfaces of the circuit boards. The cap may hold the circuit boards in their respective slots.

LED lamp with LEDs on a heat conductive post and method of making the LED lamp

A lamp assembly is provided which includes a low pressure discharge lamp disposed between a light bar and a housing. The light bar provides internal reflection of light reflected by the lamp from an input surface to an output surface. The light bar and the housing collect electro-magnetic interference generated by the lamp.
